Determine the intervals on which the function is concave up or down and find the points of inflection. y = 19x + In(x) (x > 0) Provide intervals in the form (*, *). Use the symbol o for infinity, U for combining intervals, and an appropriate type of parenthesis "(", ")", "[", or "]", depending on whether the interval is open or closed. Enter Ø if the interval is empty. Provide points of inflection as a comma-separated list of (x, y) ordered pairs. If the function does not have any inflection points, enter DNE. Use exact values for all responses.

Determine the intervals on which the function is concave up or down and find the points of inflection. y = 19x2 + In(x) (x > 0) Provide intervals in the form (*, *). Use the symbol ∞ for infinity, U for combining intervals, and an appropriate type of parenthesis "(", ")", "[", or "]", depending on whether the interval is open or closed. Enter Ø if the interval is empty. Provide points of inflection as a comma-separated list of (x, y) ordered pairs. If the function does not have any inflection points, enter DNE. Use exact values for all responses. concave up: concave down: (х, у) %3D

For each problem, find the x-coordinates of all points of inflection, find all discontinuities, and find theopen intervals where the function is concave up and concave down.   y = 1 / ( x-3)
